Title: Mehtod of welding iron steel and non-ferrous alloys
IPC: B23K9/09
Filed: 1971-10-13
Abstract: 1363450 Welding by fusion NIPPON STEEL CORP 13 Oct 1971 [13 Oct 1970 24 Oct 1970 17 Nov 1970 1 Dec 1970 24 March 1971] 47707/71 Heading B3R In consumable electrode wire arc welding of iron, steel or non-ferrous alloys, in any position, wherein to improve weld metal properties the welding current is increased and decreased periodically, wire feed speed is increased and decreased respectively and in synchronism with the current increase and decrease to control arc length, e.g. to maintain the latter constant, and welding torch travel speed is varied in a fixed relationship to the welding current varistor. Further, the electrode wire may be transversely oscillated. The invention may be applied to gas shielded (using solid wire), gas shielded or unshielded (using a tubular flux-cored wire) or submerged arc welding. Current, wire feed and torch travel may be changed by magnetic amplifier, feed motor current and travel motor current control respectively. In Fig. 2a, 2b, 2c, the current i changes between I 1  for a period t L  and I 2  for a period t H , the wire feed speed v and torch travel speed are changed, in synchronism, between V 1  and V 2 , and S 1  and S 2 . The periods t L  and t H  may lie between 0À1 and 3 seconds. Described electrode wire oscillations include a single cycle S.H. or triangular wave motion, Fig. 2(d), or a double cycle S.H. motion, Fig. 3 (not shown), only in the periods t H ; a single cycle S.H. motion only in the periods t H  with the oscillation rest position at one wall of the weld preparation, Fig. 4 (not shown); and, in fillet welding, half cycle motions alternating oppositely in the periods t H  with torch travel speed increased only every other period t H  (Fig. 6, not shown). The number of electrode wires may be varied to prevent fluctuation in quantity of weld metal deposited; e.g. in butt jointing of pipes, in vertical-up welding three wires may be used with a fast torch travel speed and in vertical-down welding a single wire may be used with a slow torch travel speed. The Specification includes examples of butt and fillet welding including the use of A and CO 2  mixture shielding gas, steel backings, and consumable wire electrodes including 0À68- 0-8% Si, 1À55-1À63% Mn.

Abstract: 1,072,848. Cutting girders and like profile bars. P. C. PEDDINGHAUS and W. PEDDINGHAUS, [trading as PAUL FERD. PEDDINGHAUS]. Dec. 17, 1963 [Oct. 8, 1963], No. 49706/63. Heading B3W. A hand operated shear has a plate which is connected to the movable cutter and on one end of which there is rockably mounted a hand lever formed with teeth which engage a toothed segment on the machine frame and is characterized in that on the rocking axis of the lever there is mounted a counter-balancing torsion spring one end of which bears on the lever and the other end of which is anchored to the pin on which the hand lever is mounted. The machine comprises a frame 1 and two plates 3 (4) pivoted to the frame at 5. Between the plates is a hand lever 7 which pivots on pin 9 fixed in the plates and which has teeth which engage a segment 10 secured to the frame. The movable shearing cutter is actuated by a pin 6. The weight of the handle is counter-balanced by a torsion spring 13 which is mounted on an extension of the pin 9. One end 12 of the spring engages in a slot or hole 11 in the pin and the other end bears against the lever 7, the spring characteristic being approximately sinusoidal so that as the turning moment of the lever 7 increases the restoring force of the spring increases at the same rate. Two springs may be provided as shown in Fig. 3. The initial spring tension may be varied by having a plurality of angularly spaced holes or slots in the ends of the pin and selecting the appropriate slot to provide the required tension. In the embodiment shown in Fig. 5 the initial adjustment is infinitely variable the springs being mounted on round bushes 22 which are screwed on the pin 19 and which have slots 23 in their outer end faces. The ends 17 of the springs engage in the slots 23 and the bushes can be rotated to any position. The restoring force of the spring is modified by the rotation of the pin 9 about the centre 5 which has the effect of reducing the angular movement between the two ends of the spring to less than the angular movement of the hand lever.

Abstract: 1501371 Making electromagnetic windings; composite castings SBW ENGS Ltd 30 Jan 1975 [30 Oct 1973] 50348/73 Headings B3A and B3F [Also in Division H2] A double-layer electrical winding, e.g. for an A.C. or D.C. motor or generator, or a D.C. electromagnet is made by forming a core from two sets of laminations each having apertures so as to form two layers of slots in the core, filling the slots with conductive material to form the windings, and connecting the conductors of one layer with those of the other layer by end windings cast in situ. Fig. 1 shows the central part of a core assembled from inner laminations 11 with apertures 15 and outer laminations 12 with apertures 16. Central apertures 13 are provided for a shaft. The apertures are aligned by using notches 17, 18. Inner and outer laminations are separated by a layer 14 of alumina, and individual laminations are also preferably insulated from each other. When correctly assembled, the laminations are bonded together or otherwise held fixed. End sections 20, Fig. 2, are assembled so as to form skewed conductor slot portions, and the central sections may also be non-linear, depending on the type of winding desired. If there is not need to pass magnetic flux in the end sections 20, their apertures may be of larger size than those in the central portion. Apertures 15, 16 are preferably about equal in cross-section, and may be elliptical. The inner surfaces of the slots formed in the core are then coated with insulation, and aluminium is cast into the moulds to form windings, by centrifugal casting, gravity die casting, pressure die casting, or pore-free die casting, the latter involving filling the moulds with oxygen prior to casting. End connections 19 are cast at the same time using removable moulds, and may act also as cooling fins. The connections 19 at one end, or part of the peripheral surface at one end of the core, may be machined to form a commutator, or a commutator may be attached to the end connections 19 by pressure or electron beam welding, or to a machined end portion of the core. The whole of the outer surface of the core may be machined to expose the windings, in which case the apertures 16 have inward projections to retain the windings. In modifications, the end sections are formed from refractory material and the windings may be formed by forcing copper conductors through the slots.
